Note 1) REC., OFF in the condition description, expresses that MODE is REC. and NR is OFF. The same for the following.
Note 2) Obtain the input voltage of REC. – IN when the output voltage of REC. – OUT becomes 388mVrms. For this input
voltage, the reference level in REC. is assumed 0dB.
Note 3) Obtain the input voltage of PB. – IN when the output voltage of REC. – OUT becomes 388mVrms. For this input voltage,
the reference level in PB is assumed 0dB.
